//================================第一个 ajax的前置拦截器
//1 使用axios前置拦截器，让所有的请求都携带uToken
axios.interceptors.request.use(config=>{
  //携带token
  let token =  localStorage.getItem("token");
  if(token){//如果能取到token true
    config.headers['token'] = token;
  }
  return config;
},error => {

})
//===========================================ajax的后置拦截器
//2 使用axios后置拦截器，处理没有登录请求
axios.interceptors.response.use(result=>{
  console.log(result.data);
  let data = result.data;
  if(!data.success && data.msg==="noLogin"){
    // location.href = "/login.html";
    router.push({ path: '/login' });//如果你没有登录跳转登录页面
  }
  return result;//直接返回
},error => {
  Promise.reject(error);
})

//===============================================静态资源拦截器
//前端的登录拦截器   拦截路由
router.beforeEach((to, from, next) => {
